Let's say I have nodes with the following paths:

    /chapters/university-of-florida/classrooms/class1
    /chapters/university-of-chicago/classrooms/class2
    /chapters/ucla/classrooms/cla

I'd like to display a custom block I created on these URLs, but I don't want it to show on:

    /chapters/university-of-florida/
    /chapters/university-of-chicago/
    /chapters/ucla/

Any ideas how to accomplish this? Note that there will be new chapters and classrooms being added all the time, so I don't want to have to manually specify the paths.

I think the [Context][1] module could work here, but I am not sure how to specify the exclusions...

Any tips?
